INVENTOR. Harry B. Miller BY Attorney clrusetts Filed Mar. 7, 1960, Ser. No. 13,141 2 Claims. (Cl. 242-128) .Ihe present invention relates to yarn retaining devices and more particularly relates to such a yarn retaining device adapted to retain the transfertail linkage of a reserve supply in readiness to be supplied to a winding machine.

In the following specification and claims the term yarn is used in a general sense to apply to all kinds of strand material, either textile or otherwise, and the designation package is intended to mean the product of a winding or twisting machine, whatever its form.

One type of winding machine commonly used in the textile industry is known as an automatic loom winding machine and is fully disclosed in United States Patent No. 2,764,362 issued May 19, 1953, .to W. V. Goodhue et al. for Method and Means for Automatically Winding Filling Bobbins in ,a Loom and Supplying Them to the Shuttle Thereof. For reasons of economy it is common practice when winding yarn on an automatic loom winder to mount a plurality of supply packages adjacent each other. Each supply package is wound in a manner whereby the inner package end is retained outwardly of said package. This end, often referred to as a transfer tail, may be tied to the outer package end of an adjacent reserve supply package thereby forming a transfer tail linkage between the two packages to provide a continuous and uninterrupted yarn supply to the winding machine.

Such linking of the transfer tail of one supply package to the outer end of an adjacent reserve supply package necessarily creates a loop of yarn in the area between the two packages. Similarly a transfer tail not so linked will hang loosely from its package during the unwinding of the supply package. Unless this loop of yarn or transfer tail is contained in some manner it will be gyrated.

about during the winding operation and thereby exposed to the deleterious effects of such movement as, for example, premature unwinding, twisting and breaking.

It is, therefore, one object of the present invention to provide a device for retaining a transfer tail linkage connecting two supply packages.

Another object of the present invention is to provide a device for retaining a transfer tail linkage connecting two supply packages which upon the depletion of one package permits the yarn contained in the second package to be drawn off.

Another object of the present invention is to provide a device for yieldably retaining a transfer tail linkage connecting two supply packages and simultaneously supporting the transfer tail end of the reserve package to retain said end against premature unwinding.

Another object of the present invention is to provide a device for yieldably retaining a transfer tail linkage which facilitates easy and rapid threading of a strand therethrough.

Another object of the present invention is to provide a device for yieldably supporting a transfer tail linkage which is inexpensive to manufacture and durable and reliable in use.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the apparatus possessing the construction, combination of elements, and arrangement of parts which are exemplified in the following detailed disclosure, and the scope of the application of which will be indicated in the claims.

\ United States Patent For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings wherein:

FIG. 1 is a plan view of the present invention mounted on the supply bracket of a winding machine with a transfer tail linkage and a transfer tail engaged therein.

FIG. 2 is a perspective view of the present invention.

FIG. .3 is a sectional view taken along lines IIIIII of FIG. 2.

FIG. 4is a view similar to FIG. 2 but showing the yarn holding disc lifted to reveal details of construction.

FIG. 5 is a top plan view of the device of FIG. 2.

Referring now to the drawings wherein a preferred embodiment of the present invention is disclosed. A

a member 10 conveniently mounted on a winder or other textile machine (not shown) is bifurcated to define package supporting arms .12 and 14. Arms 12 and 14 mount packages P and P respectively in a suitable manner whereby said packages may sequentially supply yarn to the winder or other textile machine.

A rigid bracket 16 is fixed at the fork of arms 12 and 14 as by a bolt 18 and extends horizontally outwardly therefrom. An inverted truncate element comprising base 20 is secured to and carried on the opposing end of bracket 16 by a screw 22 which passes through said bracket to be threadedly engaged in the bottom of base 20. Base 20 is thereby fixed intermediate of supply packages P and P Said base is trepanned so as to form a pair of stepped recesses 24 and 26, the upper recess 24 being shallower and wider than the lower recess 26, as shown in FIG. 3. Lower recess 26 of base 20 has a pin or stud 28 centrally disposed therewithin and projecting vertically upwardly from the base thereof to a height level with the upper rim of base 20. Stud 28 is of square cross section and is drilled and tapped axially thereof in the uppermost section.

'A yarn supporting layer of resilient friction material 30 is positioned within recess 24 and is preferably fixed thereon, as by cementing, to prevent movement thereabout. Said resilient friction material may be of any suitable type for yieldably retaining a strand of yarn thereon, and without limiting the invention, examples of suitable friction materials are sheepskin, felt, and sponge rubber. Friction material 30 is shaped to conform to and fully occupy upper recess '24 of base 20 but affording a clearance space about lower recess 26. Friction material 30 is of suliicient thickness to extend above the upper rim of base 20 thereby aifording a surface for a flat disc or pressure plate 32 to cooperate with and be supported on.

Disc 32 includes a flat plate somewhat larger in diameter than base 20 to thereby facilitate separation of the two members. A hollow boss or shank 34, adapted to loosely enclose stud 28 depends centrally of disc 32. Shank 34 is recessed through substantially its entire length and has a bottom wall 36 having a square aperture therein to slidably engage stud 28. Disc 32 is thus freely slidable axially of stud 28 but rotation of said disc about its vertical axis and said stud which would tend to entangle a strand of yarn is prevented. Axial movement of disc 32 upward of stud 28 is limited by a screw 38 threadably engaged in the upper end of stud 28, and washer 40.

The foregoing device operates in the following described manner. A pair of supply packages P and P are positioned on adjacent supporting arms 12 and 14 of member 10 of a winder. Bracket 16 is anchored in a substantially horizontal plane between said arms. With strand of yarn Y running from supply package P to the winding means, transfer tail T on package P is tied to the outer yarn end Y of reserve package P Said tied or linked strands of yarn are then inserted between friction material 30 and disc 32 to be retained thereby. Transfer tail T of package P is also inserted therebetween. ,When the yarn supply on package P is exhausted the pull on'the winding strand by the winding means will remove transfer tail T and lead strand Y linked therewith, from the retaining means and package P will thereby commence to unwind. Transfer tail T can thereafter be removed from the yarn holding. means to be linked to the outer yarn end of a new reserve supply package replacing exhausted package P Since certain changes may be made in the above apparatus without departing from the scope of the invention herein involved, it is intended that all new matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

' What is claimed is:
